Occurs in Ankeniheny, Mandraka (Glaw and Vences 2007) at 900-1400 m asl (Raxworthy and Vences 2008). Found in leaf litter of primary rainforest, secondary forest and pine forest (Glaw and Vences 2007).

Life History, Abundance, Activity, and Special Behaviors
Habits: Terrestrial, in forest leaf litter. Calls after dusk and during the day, especially shortly after rain (Glaw and Vences 2007).

Calls: A series of 5-12 frequency-modulated melodious notes, lasting 1.5-4.5 seconds (Glaw and Vences 2007).

Trends and Threats
This species has a fragmented distribution within a narrow altitudinal range. It is found in three protected areas: Parc National de Zahamena, Parc National de Mantadia and Parc National d'Andringitra (Raxworthy and Vences 2008). Its forest habitat is being lost due to increasing agriculture and grazing, logging, charcoal manufacture, invasion and spread of eucalyptus, and expanding human settlement.

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Subtle changes to necessary specialized habitat
Habitat fragmentation
